DOUBLE-BARREL GUN.

ToaZZ 'whom t may concern Be it known that I, GEORGE H. GIDDINGS, acitizen of the United States, residing at I'lion, in the county ofHerkimer and State of New York, have invented certain new Aand usefulImprovements in Double-Barrel Guns, of which the following is aspecification. .l

This invention relates to an over and under type of double barrel shotgun. The object of the invention is to give to the sportsman a doublebarrel gun that can be handled under the same conditions as theautomatic and pump shot guns, that is it can stead 'of between twobarrels, both barrels can be fired by the one trigger, and both shellsanbe automatically ejected. A fur? ther object of the invention is tofurnish a gun of this type in which only one barrel can be used ifdesired, or either the upper or lower barrel may be fired first, thebarrels being alternately discharged.

This'gives to the trap shooter a gun which 'can be used both as a smglebarrel trap, and 'a double barrel field gun. While but one trigger isemployed the gun can be converted into a two trigger gun if desired.

A further andV important object of the invention is, to so design allthe parts that they can be machine made thereby giving the gun acomercial as well as a sporting value. s The invention also consists inthe novel features of construction to be hereafter described, pointedout in the claims and shown in the accompanying drawings, in whichFigure 1 is a side elevation partly in sec- 'tion and partly broken out,the gun being closed and hammers down, the safety button in off safeposition, and showing the right hand sear, and the trigger, in positionl for firing the upper barrel.

Fig. 2 is a side elevation of the rear por--I tion of the gun, partly insection, the gun oeing shown in full open position, the ham- ,mers 'atfull cock and the safety posts in safe position.

In constructing the gun I employ a frame 1 of the box frame type,therefor.n the hammers, main springs sears and springs are all attachedt0 the frame and not to a lock plate.

- The barrels 2 and 3, are arranged one v above the other, and to thelower barrel 2 is attached a lug 4 sunk in the frame a'nd swinging `im ajoint pin 5. The fore-end iron 6 serves to hold the parts togetherthrough the bearing it has on a barrel lug 7 dovetailed into the lowerbarrel 2.

Two hammers 8 and 11 are employed pro-y Y vided with oppositelyextending pins 10 and 13, and rear projections 9 and 12, respectively.Referring to Fig. 1 it will bel noted that hammer 8,v the left handhammer, is in the foreground with the cam portion 13 of the right handhammer 9 partly in view. These hammers are cut away on their inner.faces to receive vthe cocking lever 14, the hammers and'fthe lever 14swinging on the pin 16. This is shown most clearly in Fig. 7. Thecutting away of the hammers forms on each of them a shoulder 17, and acooperating shoulder 18 is formed on theleocking lever/ 14 adjacent itspivotal connection With ther pin 16. The cooking lever 14 has at'itsforward end a nose 15 which coperates witha cooking hook 21. The cookingshoulder 18 Aforces the hammers back to full cocked position when thecooking lever 14 is forced upwardly by engagement of the nose l5 withthe hook 21, when the gun is opened. The cooking hook 21 is pivoted in aslotted portion of the barrel lug 4. "vAi'lat spring 22 secured to thelower barrel at the breech bears on the pivoted end of the hook 21 andnormally tends to hold the hook out of engagement with the nose 15 ofthe cocking lever 14, so that the barrels can be disconnected from theframe when desired. r1`his spring is counteracted by a two part plunger25 cushioned with a coil spring 26, the plunger being loosely mounted ina bore formed in the lug 4 and bearing at one end on the joint pin 5 andat the other end on the cocking hook 21 when parts are assembled.

23, best shown. in Fig. 8. These springs are mounted on pins 24, thesprings bearing at islformed by a yoke .by the plate their lower ends onsuitable collars on the pins and the lower portions of the pins, belowthe collars are flattened and concaved or recessed on their ends, so asto bear on the pins 10 and 13 of the hammers, as shown in Figs. 1 and 8.

To lock the barrels when' in closed position I provide on the barrelstwo rearwardly projecting side lugs 28, most clearly shown in Figs. 2and 6 and in the frame I mount; slidable coperating bolts 29, which aremovable rearwardly to disengage the lugs by a top lever 30.

.Gonnection between the bolts and lever 30 31, the bolts having intowhich lit lugs 31n carried 31. A coil spring 32 normally holds thebolts`in looking engagement with the lugs 28, the spring surrounding a.rod 33 which bears at one en on a bearing stud 34 carried by the plate31 and at its rear end the spring rod is steadied by passing through astud 35 screwed intov a tang 36 of the frame.

The yoke is connected to the lever plate 30 by means of a screw 37.Lateral moyementof the top lever will carry the yoke and boltsrearwardly, rearwardly through the stud 35 and compressing the spring 34and the stud.

ln connection with my lock mechanism, to make the same perfectly sa fe,I employ a safety device as follows:

A spring 38 is arranged to slide on the under -face of the tang 36 andlying flat on the under face of this spring is a safety post support 39to the forward end of which are hinged the safety posts 40. A safetygrooves 29 hammers being held in.

. in Fig. 2.

moving the rod 33- 32 between the kbearing 3, for a distance button 41is slidable on the tang and the stem of the button extends through asuitable slot in the tang and through the spring 33 and support 39,being held by transverse pin 42. The rear end of sprin 38 is rolled orcoiled to engage a detent 43 1n the underside ofk the tang 36. Thisdetent holds the spring and posts in forward or olf safe osition. v

A safety push rod 44 straddles a main tang screw 45 and engages theforward end of the post support 39. The tang 36, being held in place by`the screws 45 and 47, isl

readily detachable by loosening said screws.

`When the lever 30 is pushed laterally, moving the bolts 29 rearward.rod 33, working through stud 35, engages the push rod or bar 44 andcarries with it the posts, sup-l port, and spring 38.

'lhisearries the button and spring to their safe position, held there byengagement of the spring 38 with a second detent 43a. But the safetyposts 40, which are hinged, do not immediately go lo safe position butare held off by Contact with the rear upturned ends of sears 26 and 27,as at 26"L and 27a, the posts then occupying positions intermediate thepositions shown in Figs. 1 and 2.

This is due to the fact that the forward ends of the sears are depressedby bearing against the hammers, 8 and 11 keeping the rear ends of thesears elevated. But when the hammers have reached full cock the forwardends of the sears have been released and their forward ends raised bysear springs 2Gb, one of which is shown in Fig. 2, and under pressure ofsaid springs the rear ends of the sears assume the position shown Asshown the front end of spring 38 is bent over and downward and splitforming depending forks 38a that bear on the fronts of the hinged posts40. This forms an ijn-` dependent spring for each post whereby the ostsare at the proper time, on full cooking of the hammers, forced over therear ends as shown in Fig. 2, thereby making the gun absolutely safe, asthe gun cannot be `discharged either by jars or pulling the triggeruntil the safety button has been moved forward.

All of the safety mechanism is carried by the detachable tang whichpermits easier adjustment of the parts while the gun is being assembledand also reduces the percentage of broken tangs in course ofmanufacture.

The breech portion 2,, 3EL of barrels 2 and of about three inches, viz.where most of the mechanism is placed, is formed separate from thebarreltubes 2 and 3, the breech block being bored somewhat larger thanthe then assembled and connected to the breech block by shrinking thelatter.

A side rib 2b is employed on each side, be-

chambers and the tubes are ing soldered in position. This elieapens thelconstruction by reducing cost o f 'manufacture.; The fore-end 6 islocked to the barrels I byyformingji-nfit. asvlotethrough which, ex-

.h'elphook is. corrugate'dfto ,form a thumb ieeeyextending asufiicientdistance out of l the slot for this purpose.

The devices above described taken together form a complete operativegun, all parts cooperating together for the accomplishment ofthepurposes described.

In addition to these parts I have'shown certain shell ejecting devicesA, B, C, and D and single trigger devices, F, G, and H by means ofwhichthe trigger E can be set for the iiring of either the upper or thelower:`v

barrel.
